In order to restore a certain amount of useful visual field, it is necessary to greatly magnify what the patient sees.

1 cm) and 21 times the distance between the eyes must be maintained precisely. Magnifying glasses have a very limited field of view (with a
In the case of a magnifying glass with cI11 and magnification x3, the field of view is 3t*), and the effective working distance is short and it is inconvenient to use. Telescopes are used to view distant objects and therefore have a long effective working distance. However, the telescope must be light in weight and has a very limited field of view (from less than 20 degrees at ×2 magnification to 4 degrees at higher magnifications to obtain a comfortable field of view). The minimum field of view required for this is 30 degrees, which is extremely narrow). ni oester

This can also be achieved using a spectacle magnifier. This optical system is inconvenient when using glasses with high refractive power, and it can even be said that the degree of freedom when wearing it is lower than that of other systems (in the case of a refractive power of +300, the variable optical distance between the eyes is must remain within 11R1R).

It is something to do. The present invention achieves magnification of distant objects without reducing field of view by providing a single intraocular lens element incorporating a reflective surface that creates the effect of a folding telescope with a long focal length. Katadai of Trick・

Additional visual magnification can be achieved by using spectacle lenses, in which case the total magnification is similar to that of a microscope (refracting power x8), while the field of view and effective working distance are kept at practical values. Can be maintained. The actual shape of the lens may vary depending on the shape of the patient's eyes, the required magnification, and whether or not the patient wears glasses.

の適当する反射性材料で形成することができる。Since the telescopic effect occurs within the eye itself, the field of view obtained by the lens element of the invention is considerably wider than that obtained by external magnifying means and is aimed at increasing the overall refractive power. This leaves room for the supplementary use of extra-magnification means. Lens element 10 may be constructed of any of the medical grade plastic materials commonly used in intraocular lens systems, such as PMMΔ. The reflective surfaces 2o and 22 are embedded in the lens element 10 in a known manner during fabrication.
